any aro can have potential... if your talking about
the potential of your rtg intensifying its color and
overall contrast of the arowana here's a couple
things you can do...
1. feed food high in vitamin A since vitamin A is what
intensifies the color/contrast.
a few things i'd recommend if you can get them is centipede,
lizards or usually house geckos and shrimp. if you can get
these i recommend getting live cb ones or if its wc make sure you
quarantine them first and gut load them for additional nutrition.
oh ya you'll have fun watching them eat centipede and lizards too
as arowanas love to eat lizards and centipedes.
goodluck with your aro, still looks nice btw
